Prompt Optimization And Semantic Understanding

via “prompt-caching-with-semantic-deduplication”

Python SDK, Proxy Server (AI Gateway) to call 100+ LLM APIs in OpenAI (or native) format, with cost tracking, guardrails, loadbalancing and logging. [Bedrock, Azure, OpenAI, VertexAI, Cohere, Anthropic, Sagemaker, HuggingFace, VLLM, NVIDIA NIM]

Unique: Implements dual caching strategy: exact-match caching for identical prompts plus semantic caching using embeddings for similar prompts, with integration to provider-native prompt caching (Claude's cache_control tokens) to achieve multi-layer cost reduction

vs others: Combines exact and semantic caching unlike simple key-value caches; integrates with provider-native caching to achieve 25-50% cost reduction on cached requests vs. no caching
